Abstract
The utility model relates to an engine electric starting clutch which includes a clutch gear, an internal clutch wheel and a fixed plate; the clutch gear is provided with an external friction ring and an internal friction ring; the internal clutch wheel is arranged between the external friction ring and the internal friction ring; the internal ring of the internal clutch wheel is opened with uniformly distributed wedge-shaped troughs which are provided with a rolling column, an ejector rod and a spring; the fixed plate is fixedly connected with the internal clutch wheel; the center of the fixed plate is provided with a crankshaft installation hole; the external ring of the internal clutch wheel is also provided with uniformly distributed wedge-shaped troughs; the external ring wedge-shaped troughs have the identical inclined direction. The wedge-shaped troughs are provided with rolling columns, an ejector rod and a spring; the rolling column is contacted with the internal radius of the external friction ring. The friction parts of the utility model are not easy to be damaged; for the one hand, the clutch is insured to be reliable; for the other hand, the utility model is helpful for prolonging the service life of the clutch.
Description
Technical field
The utility model belongs to engine art, and the electricity that particularly relates to a kind of motor starts clutch.
Background technique
The electricity of the motor of Motor Vehicle such as motorcycle starts clutch and comprises clutch gear, interior clutch pinion and fixed tray, and clutch gear has external friction circle and interior dead turn, and interior clutch pinion is contained between external friction circle and the interior dead turn.The existing electromechanics startup clutch that starts only has uniform wedge slot at interior clutch pinion inner ring, roller, push rod and spring are housed in the wedge slot, when engine start, only rely on the startup of the frictional force realization bent axle of interior roller of wedge slot and interior dead turn, the outer rim of interior clutch pinion does not have rubbing action, so just cause interior dead turn, roller, push rod, the easy friction damage of spring, cause the unreliable even inefficacy of clutch work, and working life is short.
Summary of the invention
The purpose of this utility model provides the dynamo-electric clutch that starts that starts of a kind of reliable operation, long service life.
For achieving the above object, the utility model adopts following technological scheme: a kind of electromechanics that starts starts clutch, comprise clutch gear, interior clutch pinion and fixed tray, clutch gear has external friction circle and interior dead turn, interior clutch pinion is contained between external friction circle and the interior dead turn, interior clutch pinion inner ring has uniform wedge slot, roller is housed in the wedge slot, push rod and spring, fixed tray is fixedlyed connected with interior clutch pinion, the fixed tray center is provided with the crankshaft installed hole, and interior clutch pinion outer ring also has uniform wedge slot, and the outer ring wedge slot is identical with the true dip direction of inner ring wedge slot, roller is housed in the wedge slot, push rod and spring, roller contacts with external friction circle internal diameter.
On the interior clutch pinion outer rim of the wedge slot slope end one side, be provided with the retaining tongue.
Because the utility model also has wedge slot in the outer ring of interior clutch pinion, roller, push rod and spring are housed in the wedge slot, the roller in roller in like this when engine start in the wedge slot of clutch pinion outer ring and external friction circle internal diameter, the inner ring wedge slot and the external diameter of interior dead turn rub simultaneously, the roller of interior clutch pinion and Internal and external cycle, inside and outside dead turn are stressed evenly, friction means is not fragile, guaranteed that clutch is reliable on the one hand, also helped to prolong the working life of clutch on the other hand.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that schematic representation cuts open in the left side office of looking of Fig. 1.
Embodiment
As Fig. 1, shown in 2, clutch gear 1 has external friction circle 2 and interior dead turn 3, interior clutch pinion 4 is contained between external friction circle 2 and the interior dead turn 3, interior clutch pinion 4 inner rings have uniform wedge slot 5, roller 6 is housed in the wedge slot 5, push rod 7 and spring 8, fixed tray 9 is fixedlyed connected with interior clutch pinion 4 by screw 16, fixed tray 9 centers are provided with crankshaft installed hole 10, the outer ring of interior clutch pinion 4 also has uniform wedge slot 11, outer ring wedge slot 11 is identical with the true dip direction of inner ring wedge slot 5, roller 12 is housed in the wedge slot 11, push rod 13 and spring 14, roller contacts with external friction circle internal diameter.On the interior clutch pinion outer rim of the wedge slot 11 slope end one sides, be provided with retaining tongue 15, prevent the internal diameter of roller 12 friction external friction circles 2 behind the engine start.
